T all whom it may concern:

Be it known that T, Jnssn F. CoMs'rooK, a citizen of the United. States,residing at \Villms-Barre, in the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements inVVinding-Machines, of which the following is a specification.

This invention relates to machines specially adapted for winding wire onforms for armatures and field coils and other similar parts; and itconsists chiefly in pivoting the winding head to the frame ashereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of a winding machineconstructed according to this invention, and showing a part of thecasing and one of the bearings in section. Fig. 2 is an end view of themachine.

A frame 2 is provided, and has bearings 8 at its upper part. A casingis'provided, and comprises an upper part a and a lower part 5. These twoparts form a cylindrical chamher 6, each half of which is half acylinder, and the two sections of the casing are secured together bybolts 8 and flanges 8'.

Two trunnions 9 are formed on the lower part of the casing, and arepivoted in the bearings 3 of the frame. A worm chamber 10 is also formedon the part 5 between its two trunnions, and this worm chambercommunicates on one side with the cylindrical chamber 6. A plate or rib12 is formed circumferentially on the outside of the worm chamber 10,and this plate has a curved slot ll l which is arranged concentric withthe axis of the cylindrical casing. This plate 12 bears against one sideof a lug 15 on the frame, and i6 is a bolt which engages with a hole inthe lug 15 and projects through the curved slot 14. The cylindricalcasing can be arranged vertically, as shown in full lines, or it can beturned horizontally, as shown by dotted lines in Fig. 2, or it can beset in any intermediate position. The casing is clamped to the frame bythe bolt 16 after its position has been adjusted. In winding coils foriii-matures, this adjustability is found to be very advantageous, theoperator is enabled to set the face-plate and the form which supportsthe coil, and which is secured to the face-plate, in a position whichenables him to wind the coil on the coil form to the best advantage.

A winding shaft 18 is journaled concentric with the cylindrical casingin suitable bearings 19 formed in halves upon the resp itl'VG sectionsof the casing. A face-plate 20 is secured on the shaft 18 outside thecasing, and a worm wheel 21 is secured on the shaft 18 inside thecasing.

A driving shaft 2% is journaled in the trunnions of the casing, and aworm 25 is secured on the middle part of the driving shaft inside theworm chamber, and gears into the worm wheel 21. A driving pulley or cone26 is mounted loosely on a projecting end portion of the shaft 24, andhas a friction clutch member 27 formed in one end portion of it. Afriction clutch member 28 is splined on the shaft 24:, and engages withthe clutch member 27. A bell-crank lever 30 is pivoted to the frame by apin 31, and is operatively connected with the slidable clutch member.

A treadle 32 is pivoted to the frame by a pin 33, and is operativelyconnected with the bell-crank lever. A spring 3 f is arranged betweenthe frame and a collar 35 on the connecting-rod 86 between the treadleand the bell-crank lever, and operates to hold the clutch members out ofengagement with each other until the treadle is depressed.

The coil form or other part to be wound is clamped to the face-plate andis revolved by the driving shaft and worm gearing as long as the treadleis held in its depressed position.

What I claim is:

1. In a winding machine, a frame provided with bearings, a driving shaftjournaled concentric with the said bearings, a casing pivoted.concentric with the said shaft and pij'oviued with means for securing itto the frame at different angles, a worm secured on the said shaft, awinding shaft ournaled in the casing to one side of the driving shaft, aworm wheel secured on the winding shaft and gearing into the said worm,and a faceplate secured on the winding shaft outside the casing.

2. In a winding machine, a frame provided with bearings, a casingprovided with trunnions arranged at one side of it and pivoted in thesaid bearings, said casing having also a worm chamber formed on itbetween its trunnions and provided externally with a fastening plate,means for securing the fastening plate to the frame with the casingarranged at different angles, a driving shaft journaled in the saidtrunnions, a worm secured on the driving shaft and arranged inall;

holding theclutch members apart,'a casing plvoted concentrlc with thesaid shaft and provided wlthrmeans for securing 1t to the frame atdifferent angles, a worm secured on the said shaft, a winding shaftjournaled in the casing to one side of the driving shaft, a worm wheelsecured on the winding shaft and gearing into the said worm, and afaceplate secured on the winding'shaft outside the casing.

In testimony whereof I have affixed my signature. 7 I
